Davinci•003 auto-replySecuring a headless WordPress setup involves securing both the WordPress backend and the frontend application. Here are some steps you can take:
1. **Keep WordPress and all plugins/themes up to date**: This is the most basic and important step. Updates often include security patches for known vulnerabilities.
2. **Use strong passwords and two-factor authentication**: This adds an extra layer of security to prevent unauthorized access to your WordPress backend.
3. **Limit login attempts**: This can prevent brute force attacks. There are plugins available that can help with this.
4. **Use HTTPS**: This encrypts the data between the client and the server, preventing it from being read or modified.
5. **Secure the REST API**: Since the REST API will be exposed in a headless setup, it's important to secure it. You can do this by requiring authentication for all requests, and by limiting the types of requests that can be made.
6. **Sanitize all user input**: This can prevent SQL injection attacks. WordPress has built-in functions for this, like
7. **Use a security plugin**: There are many available that can help secure your site, like Wordfence or Sucuri.
8. **Regularly backup your site**: In case anything does happen, having a recent backup can save you a lot of trouble.
Here's an example of how you might secure the REST API by requiring authentication for all requests:
This code will return a 401 error for all unauthenticated REST API requests. You can add this to your theme's functions.php file.

Here's an example of how you might secure the REST API by requiring authentication for all requests:
add_filter( 'rest_authentication_errors', function( $result ) {
// If a previous authentication check was applied,
// and it was successful, return that result.
if ( true === $result || is_wp_error( $result ) ) {
return $result;
}
// No authentication has been performed yet.
// Return an error if user is not logged in.
if ( ! is_user_logged_in() ) {
return new WP_Error(
'rest_not_logged_in',
'You are not currently logged in.',
array( 'status' => 401 )
);
}
// Our custom authentication check should have no effect
// on logged-in requests
return $result;
});
This code will return a 401 error for all unauthenticated REST API requests. You can add this to your theme's functions.php file.
